N2 - In order to evaluate traffic operation status of signalized intersection and improve pedestrian traffic safety under the condition of ice-snow, it was studied that the influence of ice-snow on capacity of signalized intersection and the minimum green time. Saturated headway data of nine signalized intersections were observed by video method. And the influence of ice-snow melting pavement, compacted partly snowy pavement, compacted snowy pavement and normal pavement on saturated flow rate of signalized intersection were analyzed respectively. Correction coefficients of capacity of signalized intersection on different ice-snow pavement were given. Pedestrian's crossing speed at nine signalized intersection on snowy pavement, icy pavement and normal pavement were observed and compared. And then the suggestion values of minimum green time calculation parameter were put forward.
